T0 at whom, it may concern.-

Be it known that I, ANDRE MIXNER, a citi-.

plate or film holders being held in frames hinged to the sides of thecamera, this construction insuring great facilities in fixing the platesor films in the focal plane of the camera and in removing the same afterexposure.

Further objects and advantages of the invention will appear in thefollowing description of a book-camera built on this system.

In the drawings, Figure 1 is a side view of a camera holding ten plateswith the side cover removed. Fig. 2 is a top view of the closed camerawith the top cover removed, following line A A of Fig. 1. Fig. 3 is thesame View of the camera opened and ready for the first exposure. Fig. 4is a side view of the frame and the five plate-holders of one sideremoved from the camera and showing Fig. 5 is a bottom view of the samewith the frame fastened to the side of the camera before any exposurehas been made. Fig. 6 shows the same in position for'the first exposure.Fig.7 shows the same after exposure during the turning of the plates outof position. Fig. 8 shows the plate-holder frame fastened to theside ofthe camera after the first exposure. Fig.9 is a bottom view of the sameparts, four plates havingbeen exposed and the fifth and last ready forexposure. Fig. 10 shows the plates of one side after having beenexposed.

Similar characters of reference indicate corresponding parts in all thefigures of the drawings;

1 and 2 are the covers of a book-shaped camera,to be opened justlikeabook and containing fastened between them the light-tight foldingchamber, which is inclosed when folded up in a frame 3, representing thepaper edges of the book. The back contains the lens and focusing device14 and the shutter.

Two frames bearing five plate-holders each are hinged to the inner sidesof the camera case, each frame, with its plate-holders, oscillating onan axle 7, common to all of them and fastened to the bottom plate 6 andtop plate 4:. Each plate-holder bears at the bottom end farthest remotefrom the hinges a flange 8, the flanges of one set being arranged onenear the other in a row. The plate-holders are held close together bymeans of a slider 9, sliding on the bottom of the frame and bearing anopen slot at one end to embrace the flanges 8 of the plate-holders. Theslider is held in position by a spring 10, bearing a pin catching in aroW of holes in distances corresponding to the breadth of the flanges 8.into and out of position by aid of a doublebent lever 11, fastened tothe side cover and extending through the bottom of the camera. A finger20, governed by a spring, is fastened to the camera-case next to the rowof flanges 8. To get this finger to retain the plate-holders one afterthe other by aid of their flanges 8, the frame and the plate-holders aremoved a little distance farther toward the finger 20 after the plateshave been exposed, thus bringing the latch of the plate-holder inquestion into contact with the finger.- This is effected by aid of aspring-governed trigger 1 8, fastened to the bottom plate 6 of the frameand catchingin a ratch 17, hearing five ratch ets. The trigger beingpressed against the ratch and the lever 11 embracing with a slot 12 thescrew 13, fastened to the'bottom plate 6, the trigger catches in thenext ratchet each time the plate-holders are swung in again. Thus theframe carrying the plate-holders is driven a little forward. A springdevice 40, catching in a row of holes in the side plate 15, preventsthis forward movement from being extended too far. A catch 19 serves toprevent the slider 9 from following this movement of the frame 6 bycatching its shoulder 21.

To make an exposure, the camera is opened and one of the plate-holderframes swung into position, Figs. 3 and 6, by turning its re spectivelever 11. After the exposure the plate-holder frame is swung in againbya contrary motion of the lever. The trigger 18 The plate-holder frameis swung' catches in the first ratchet of the ratch 17,-

Fig. 7, and the closing motion of the frame drives the frame andplate-holders forward by the breadth of one ratchet. The slider 9 beingcaught by the catch 19 sets free the flange 8 of the plate just exposed,said flange having moved behind the finger 20, Fig. 8. The next time theframe is'swung out for an exposure the first plate already exposed isre-' tained by the finger 20, and the second plate is now placed in thefocal plane. The closing of the frame brings the next plate-holddersflange behind the finger, and on the frame being swung out a third timeplates I and II are retained, and so on. Figs. 9 and 10 show theposition of the working parts when the last plate of the set is exposed.

I claim- 1. The combination with a camera-case, of a plurality ofplate-holders, and a common axle carrying the plate-holder framessecured to the sides of the camera-case and extending paralleltherewith, said plate-holders carrying the unexposed plates restingnormally out of exposing position, themotion of said frames beingpositively controllable from without the case, substantially asdescribed.

- 2. The combination with a cam-eracase, of one or two plate-holderframes hinged to the sides of the camera-case, the camera-cas'eha'v"-ing a book-like shape, said case, comprising the folding sides, thebellows and a fixed'por tion intermediate of the ends of the sides towhich each side is hinged, said portion formin g the lens-holder,substantially as described.- 3. The combination with a camera-case, of

one or two plate-holder frames hinged to the sides of the camera-case tomove toward and from the same, and a lever extending outside of thecasefor positively moving the holder carrying the unused plat-es from theposition toonesi'de of the exposing position into ex v posing position,substantially as described. I 4. The combination with a camera-case, of

a pivotally-supported plate-holder frame hinged to the sides of thecamera-case, means for controlling the motion of said frame from withoutthe case, all of the holders normally i occupying a positiontoon'e sideof the expos-- ingposition, and means for retaining some of. theplate-holders,vwhile the others are swung out with the frameintoexposing position,

thesides of the camera-case, means for con trolling the motion of saidframes from withoutthe casesaid means com-prising a twicebent crankpivoted to the side'and extending.

through the bottom of the case, said crank Q being movably fastened tothe bottom of the frame, substantially as described.

6; The combination with a camera-case, of a plate-holder frame hingedto'thesidesof the camera-case, means f0r'controlling.themotion of theframe from without the case, plate-- holders carried by the frame,projections carried by said holders and means for engaging saidprojections to retain the holder carrying the used plates out ofengagement with said frame, substantially as described.

7. The combination with a camera-case, of'

' a plate -ho'lder frame hinged to the sides of the camera-case, meansfor controlling the motion of said frame from without the case, plateholders, projections arranged in a row carried by the same, a sliderbearing a shoulder at one and an open slot at the other end, said .slotembracing the projections of the plateholders, substantially asdescribed.

8. The combination with the camera-case, of plate-holder frames hingedto the sides of the camera-case,--means for controlling the motion ofsaid frames from without the case, plate-holders, projections carriedthereby arranged in arrow, and a spring-governed finger to retain theprojections that are driven behind it, substantially as described.v

. ratchet fastened to-the-camera-case and bearing as many r'atchetsasthere-are plate=h0lders, a spring-governed trigger fastened to thebottom of the frame adaptedto catch in said ratchet, whenever theframeis-swu'ng against thes-ide of the camera-case, substantiallyasdescribed.

i 11. The'combination with a camera-case, of aplate-holder frame hingedto the side of the 3 camera-case, means for controlling the motion 50fsaid frame from without the case, plate -holders, projections-carriedthereby arranged gin afrow, a sprin-grgoverned finger retaining theprojections that are driven behind it, means for moving the plate-holderframes toward the finger including a flange-embraciing slider anda catchfor preventing said 2 slider from following the motion of the frame,substantially as described.
